Strain Description

Northern Lights seeds produce short, compact plants that bloom fast and abundantly. They are renowned for dense, resinous buds emitting a pungent aroma of pine, citrus, sweet spice, and earthy undertones. Effects include tranquil body relaxation paired with mild cerebral uplift—well-suited for nighttime use or stress relief.

Growing Information

Northern Lights is exceptionally beginner-friendly and performs reliably both indoors and outdoors. Flowering completes in 8–9 weeks under a 12/12 photoperiod. Grow indoors in moderate, nutrient-rich soil or hydroponics; outdoors, choose a warm, sunny site. Expect yields up to 400–500 g/m² indoors and up to 550 g per plant outdoors. Good ventilation and training (like SOG or LST) enhance airflow and minimize mold risk.

Quick Grow Tips

Lighting: 18/6 veg phase, switch to 12/12 for flowering; blooming completes in 7–9 weeks.

Nutrients: Moderate feeding; avoid excess nitrogen during flowering to maintain resin quality.

Watering: Keep soil moist but well-draining; avoid waterlogging.

Environment: Grow in climates between 70–85 °F (21–29 °C) with humidity around 40–50%; maintain airflow to prevent mold.

Extremely happy with the process involved. Being a first time grower I knew nothing about nothing when it came to this medicine and how to grow it. I did my research and when it came time to buy seeds one name kept popping up in my searches, cropking. So I gave them a try, and even when I had some trouble spoke with someone immediately and helped me out quick and easy. Would recommend again and again and again. Not to mention.l two extra seeds thrown in was a nice surprise.😉

We got a new environment for my plants. I setup a new one, more spacious for more growing plants. So I bought this one, another try.
I got variety of strains already. All successful from Cropking. I love these seeds, they are a healthy and taller plant. Really good for all pain reliever. Good for mood swings. All the strains I tried are great!

Red Bud – June 20, 2020

Seeds took 6 weeks to arrive. Robust healthy plants we easy to grow. Auto flowering started at ~7 weeks, so not sure how useful this auto feature is compared to just going 12/12 from the start. Yield as advertised. Potency, flowering time, as expected. Buds were a bit airy and variable from plant to plant compared to other vendor NLAs. Size was variable from plant to plant. Enjoyable product.

4 stars, for an auto. I grew a side by side test of Crop King NL auto with other seed vendor NL autos. I found CK NLA to be a repeatable auto at about 8 weeks and about 8 weeks more to harvest. I found the strain to be more consistent plant to plant than other autos. While plant to plant size was variable, but repeatable bud structure, potency and yield regardless of plant size. Yield was in the lower half range of the advertised in grams/m2. Effects were as expected from an Indica plant. My only real critique is that the bud structure is relatively loose compared to other NLA seed vendors and that shorter time from germination to harvest and higher yields can be achieved on non-auto NL from other seed vendors as long as you are willing to put a timer on your light and go 12/12 earlier than the automatic 8 weeks.
